Proposition 2.2.8. If a is positive and b is a natural number, then a+b is positive (and hencee b+a is also, by Proposition 2.2.4). We can use indcution on a or b, let's try both! Proof 1. Use induction on b. For the base case b=0, we have a+0=a, byLemma 2.2.2....

If you want to find the sum of positive numbers, the condition should be “>0”, because, in order for a number to be considered as positive, it has to be more than 0. So to sum up only positive values from the range B2:B10, the SUMIF function will be: = SUMIF(B2:B10, ">0...

we know that the second term can be expressed as a⋅r notice if we multiply S−Sr=a by r, we would get r(S−Sr)=ar⇒Sr−Sr2=1⇒Sr2−Sr+1=0 This quadratic has real solutions if the discriminant is greater than or equal to zero, or S2−4⋅S⋅1⩾0 This yields...
